Description
Technical field
The invention belongs to construction timber technical field, be specifically related to a kind of side utilizing mud and mud to fire sponge brick
Method.
Background technology
The development in city, wetland, the minimizing in greenery patches so that city occurs in that problems.Rainstorm weather, limited row
Water measure makes urban parts location waterlogging occur, has had a strong impact on the safety of resident, has carried various to the development in city
Uncertain factor.Waterproof pavement has blocked and has oozed under rainwater, causes rainwater can only be arranged by special sump, storm sewer
Put.This drainage system the drainage works under being unsatisfactory for extra torrential rain.
Armored concrete building, cement pavement etc., the tropical island effect for city has material impact.City underlying surface,
Such as concrete road, asphalt road etc., specific heat is little, and heat absorption is fast, and under identical solar radiation, temperature quickly raises；And it is such
Hyposmosis road surface, has intercepted the evaporation of the following steam in road surface, and heat is difficult to dissipate, and exacerbates tropical island effect.
Existing baking bricks in technique, using clay (including gangue, shale powder) is primary raw material, in " limit viscous prohibit real "
Under policy conditions, the use of clay material is very restricted.Existing frequently-used high osmosis water-permeable brick, mainly uses pottery
Or coarse granule cement material makes, cost cost is big.And mud in city, mud yield are the biggest.Dredging silt solid phase mainly by
Clay mineral forms, generally Organic substance, calcination in the case of roasting in mud, and forms pore channel, advantageously forms sea
Continuous brick.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides one and become silted up with dewatered sludge of urban sewage plant and dredging
Mud is primary raw material, burns out a kind of good water permeability, meets as Route for pedestrians rheobase requirement, and has water conservation, reduction of heat work
The method of sponge brick.
For achieving the above object, present invention employs techniques below scheme:
A kind of method utilizing mud and mud to fire sponge brick, comprises the steps:
S1, dewatered sludge, mud, cement, waterglass are stirred；
S2, the compound feeding brickmaking machine that will stir, be pressed into adobe；
S3, by green compact at room temperature maintenance and be dried；
S4, dried green compact are put into kiln and are sintered, and prepare sponge brick.
Preferably, in step S1, in terms of mass fraction, dewatered sludge account for 35～70%, mud 10～50%, cement 3～
10%, waterglass 1～5%.
Further, the wet basis moisture content of described dewatered sludge is 60～85%；The moisture content of described mud be 45～
65%, cosmid (particle diameter is less than 5 μm) content is more than 30%, at stirring front row except bulky grain foreign material in mud.
Further, described cement is Portland cement, is numbered OPC32.5；Or employing quick hardening sulphoaluminate
Cement.
Preferably, using twice paddling process in step S1, mud, mud, cement three kinds mix the mixing speed of material and are
300～500r/min, mixing time is 5～10min；Add the mixing speed after waterglass constant, mixing time be 10～
15min。
Preferably, in step S3, green compact curing time at room temperature is 3 days, and baking temperature is 90～105 DEG C, when being dried
Between be 8～12h.
Preferably, in step S4, sintering temperature is 1050 DEG C, and sintering time is 6～9h.
Preferably, the described sponge brick porosity that step S4 prepares is 40～60%, and infiltration coefficient is 1.2 × 10-2～6.2
×10-2cm/s。
The beneficial effects of the present invention is:
1), this method uses mud and mud at high temperature to ensure that the cement of intensity, waterglass conduct by adding
Cementing material, is fired into the novel floor tile being applicable to sea urban construction, i.e. sponge brick；Ensure that sponge brick had both had the biggest
Porosity ensures again the highest intensity.Containing substantial amounts of organic matter in mud, in roasting process, organic calcination, generate certainly
Right concrete dynamic modulus passage, the beneficially formation of sponge brick pore channel；The sponge brick infiltration coefficient prepared is 10-2Cm/s quantity
Level, reaches as water-permeable brick GB/T25993-2010 " permeable pavement brick and porous pavement plate " the permeable class requirement of B level.
2), general mud, mud brickmaking in prior art, must mummification or reduce moisture content, Yi Mian largely
Sintering procedure occurs volume contraction or be full of cracks；And utilize cement and waterglass as hardened material in the present invention, it is not necessary to right
Mud or mud carry out early stage drying and other treatment, and (the wet basis moisture content of dewatered sludge is 60～85%, is general urban life dirty
Moisture content scope after waterworks sludge process；The moisture content of river and lake silt is 45～65%, for general dredging silt go out aqueous
Rate) scope can be obviously improved intensity and the hardness of sponge brick, fragment of brick surfacing, no significant defect.
3), the present invention utilize sewage plant sludge and mud as firing the main material of sponge brick, belong to twice laid,
Can not only economize on resources, can partly solve place to go and the process of river and lake dredging mud of domestic sewage factory mud simultaneously.
4) in sum, the sponge brick that the present invention is fired, hole is big, good water permeability, beneficially rainfall water drainage, increase air
Heat exchange with ground；The raw material of this sponge brick, it is not necessary to pre-treatment, process is simple；Cement, the secondary of waterglass is used to mix
Enter stirring technique, the intensity of sponge brick can be significantly improved, meet the strength demand as footpath brick；This sponge brick is adopted
Main material mud, the big garbage that need to process of the mud amount of belonging to, thus the present invention to be that offal treatment provides new
Approach, and reduce brick making cost.
